14. How much electrical energy is delivered to a 60.0 W lightbulb if the bulb is left on for 2.5 hours?
Added by Brian P.
Step 1
Given that the power of the lightbulb is 60.0 W and it is left on for 2.5 hours, we can use the formula: Energy (in Joules) = Power (in Watts) x Time (in seconds) First, convert the time from hours to seconds: 2.5 hours x 3600 seconds/hour = 9000 seconds Now, plug Show more…
